El secreto de la aceleraci\u00f3n<br \/>\nEn cuanto lanzas la moneda, empieza a girar dibujando c\u00edrculos amplios y pausados. Pero fijaos bien: a medida que se acerca al centro, el radio del giro se vuelve m\u00e1s y m\u00e1s peque\u00f1o y, como por arte de magia, la velocidad aumenta de forma espectacular. Ver c\u00f3mo acaba succionada por el agujero a toda pastilla es algo que no cansa nunca.<\/p>\n<p>Lo que estamos viendo aqu\u00ed es, ni m\u00e1s ni menos, la Ley de Conservaci\u00f3n del Momento Angular hecha realidad. \u00bfHab\u00e9is visto alguna vez a los patinadores sobre hielo?
